Bakers Modified for Steel Barrels
This works great and less expensive for more barrels:
Steel Shotgun Barrels:
Potassium Chlorate 5 %
Sodium Nitrate 6%
Potassium Nitrate 2 %
Mercuric Chloride 5%
Water qs
For a blacker and faster solution use 2% Ammonium Chloride
Etching Solution (for Pre Etch)
Nitric Acid 1 oz
Water 240 ml ( 8 oz)
Use the boiling water process, swabbing on CLEAN and prepared barrels, boil 2 minutes at a time, steel wool and continue about 10 times until desired finish is achieved. Wash with hot clean sodium Bicarbonate water and oil . Burnish with Steel wool and oil to
finish proper luster.
I modified Mr. Bakers solution to bring solubilities to more scientific levels and deleted an inert ingredient or two. I also usually add 1-3% Ammonium Chloride to help the process and found the Potassium Chlorate speeds the oxidation and quality of the job.
